BOX.

Application led July 26,

and, of course, varying in weight in accord# ance with the size of thebox and the -purpose to which it lis to be put in use, and the presentinvention has more particularly in view the means for locking thesections of 16 such a box together in assembled relation and means formaintaining said locking or interengaging means in operative position.

Boxes of this type have given excellent results, but the added material,labor and 20 waste involved in affixing or providing a locking flange onthe inner face of the upper part of the lip D of the bottom end sectionC has involved considerable expense in the total, as has also theprovisionof asimilar .:5 cooperating Aflange, on the outer face of thelower portion of the body section B, considered on a large quantityproduction basis.

The objects of the presentninv'ention are to provide a box of the abovetype of a particular construction, preferably paper covered, in whichthe locking flange or element or tongues 1 on the body section may bestamped out from the body member and will cooperate with sockets,recesses or holes stamped out of the paper board or card board materialof the lip D to form the locking or interengaging means between the twosections, the locking flange above mentioned and heretofore provided onthe upper portion of the innerA face of the lip D being l`dispensed,with.

Further objects are to so relate the parts that with any particularweight of material, and corresponding width of locking tongues 1 andcorresponding width of co` operating locking sockets, recesses or holes3, one portion 2 of the edge wall of each of the latter will engage withthe upper free side edge face of its respective tongue, and an oppositeedge portion 4 of said socket, recess or hole 3 will engage itsrespective tongue 1 at such point intermediate the sides of said tongue1 as to act asv a brace to maintain said tongue in correct position, asabove p5 mentioned, in assembled relation` and to prevent said tongue 1from springing out later- 1924. Serial No. 728,394.

ally beyond the cooperating edge wall portion 2, and to act also as abrace to prevent the deformation of said tongue under strain in normaluse, all of which objects, among others, are accomplished by theconstruction, combination and arrangement of parts, all as hereinaftermore particularly set forth, described and claimed.

In the accompanying drawings, representing but two embodiments of myinvention merely by way of illustration of the practice thereof:

Figure 1 represents a perspective View of abox embodying my inventionand broken away at several points to aid in giving a bet` terunderstanding of the details thereof, the paper covering F being omittedfor the same reason,

Figure `2, .a detail horizontal sectional view looking downward;

Figure 3, a fragmentary horizontal sectional view, broken away, lookingdownward and taken through the body section and the lip of the bottomsection on a horizontal plane coinciding with the upper side edge facesof the locking tongues in their engaging assembled relation;

Figure 4, a fragmentary perspective sectional view taken on a linecorresponding to line 5--5 of Fig. 3, of the body section and the bottomsection in superposed relation in an intermediate stage of assembly;

Figure 5, a fragmentary detail perspective View taken on line 5 5 ofFigure 3;

Figure 6, a detail cross-sectional view, on an enlarged scale, taken ona line corresponding to line 5 5 of Figure 3; the paper covering F beingillustrated on a greatly magnified scale out of proportion to theillustration of the other elements in said view; and

Figure 7, a view similar to Fig. 6, of a modification in which thecovering F is omitted.

Referring now in detail to the drawings, A designates the cover or topsection of the box, B the body section or ring, and C the bottom endsection having an edge flange or lip D.

The body section B as, preferably integral, depending spreading andbracing flanges E having their end edges mitered, said flanges, in theassembled box, lying against the upper face of the bottom end section Csubstantially at right angles to the sides of said body portion B withtheir end edges in, 0,?

substantially in, engagement to act as a bracing and spreading device tohold the lower part of the body section spread and prevent itsdeformation to maintain the locking tongues 1 in such position thattheir fi'ee upper side edge faces will be in locking posit-ion wit-hrelation to the coopera-ting upper downwardly presented, preferablyabrupt, edge walls 2 of the corresponding sockets, recesses or holes 3respectively of the lip D. Of course the exact construction of theflanges E is not essential, their function is to hold the lower endportion of the body section spread and to prevent its deformation andany element or elements accomplishing this purpose are to be consideredas equivalents.

The locking tongues 1 are formed by making inverted approximatelyU-shape cuts in the lower part of the body portion or section B,severing the material thereof on three sides and leaving the tongues 1integral with the body section, or with the respective bracing andspreading flanges E, along a line preferably coincident, as shown, orsubstantially coincident, with the line along which the respectivespreadingr flanges E fold inward, so that the inward folding of thelatter will cause the outward protiusion of said tongues 1, the materialof which they are formed and their combination with the respectivespreading flanges E resulting in said tongues 1 each being yieldinglyresilient and being yieldingly resiliently held or positioned as awhole, so that when the bottom section C is applied its lip D, inengaging with the respective outer faces of the lower portion-of thebody section B will engage the lower outer faces of the said lockingtongues or small locking flanges 1 and cause them to yieldinglyresiliently fold back toward the adjacent face of the respective outerfaces of the body section B and back into the openings from which theyare respectively cut until the upper walls 2 of the respective sockets,recesses or openings 3 formed in the lip D pass upward far enough torelease the respective tongues 1, which will then spring outward, due totheir resiliency, until stopped by the inner edge of the lower walls 4,respectively, of the openings v3, when the upper free side edge faces ofthe respective tongues 1 will be positioned directly beneath and inengagement with, or "ery closely adjacent to, the cooperating reverselypresented Walls 2 ofthe respective openings 3, all as is wellillustrated in Figures 4, 5 and 6.

Preferably a medium Weight or heavy weight of material will be used tomake a stiff box and insure a very strong positive lock or engagementbetween the box sections,

so that the box may be relied upon for use in connection with heavy.silver ware, cutglass, fancy china and the like.

Lesaiez There is an important relation between the weight and stiffnessof material used, the width of the locking tongues and the width andlocation, in a vertical direction', of the sockets, recesses, oropenings 3 in the lip D, and this is especially so where a coveringpaper F is not employed, in order that the respective tongues 1 may belimited in laterally outward swinging movement in assembling, so thattheir upper side edge faces will not pass outward beyond the verticalplane of the cooperating upper walls 2 of the respective sockets, recsses or openings 3, and so that said tongues 1, when under stress, willbe braced and in effect shortened in length so that buckling will -beprevented in any normal use, having in view of course the use the boxesare to be put to.

This relation must, of necessity, vary in accordance with the weight ofboard material and width of the tongues 1 and height of the lip D, butshould be suc-h, as illustrated, as will permitv the respective tongues1 to spring out to an extreme outward position wherein their free upperside edge faces will lie approximately fully in the same vertical planewith the cooperating walls 2 respectively, and so that the inner edgesof the lower walls 4 respectively will prevent any further outwardswinging movement as a whole of the respective tongues 1.

The bottom section C will preferably be covered with a finishingcovering F, which may be, and usually is, of paper, as is usual in boxescommonly known as papered oreovered, and the body section and top willalso preferably be papered to match.

The covering F on the bottom section C,

in addition to serving its usual function, also serves to hide from viewthe openings 3 and the tongues 1 therein and, being unifoinity pastedover the area of' the bottoni end scction C and its lip D, will alsoserve to aid in preventing the respective tongues 1 from protrudinglaterally, so that with the vpaper or other usual covering F a strongerinterengaging or interlocking construction can be obtained with a gl venweight of material, since the paper also adds its strength to resistingany lateral displacement, ensuring that any strain or pull will beexerted edgewise or substantially edgewise of the material of theinterlocking parts.

In the modification illustrated in Figure 7 the paper or other coveringF is omitted. Otherwise the construction and `operation are the same asin the preferred form. n this modification the importance of maintainingtlie correct relation between the width of the tongues land the widthand vertical position of the cooperating sockets, recess or holes 3, andthe weight of niatcrial employed, is more accentuated, since there is noadditional element to be "relied upon to prevent lateral displacement orIniS- alignment of parts. Also, where the paper covering F is omitted,as illustrated in Fig. 7, a stiff fairly heavy material shouldpreferably be used.

Of course the number and location of the tongues and sockets should bethe same on each side, where a perfectly square box is involved, orwhere an octagonal, pentagonal etc., form box is involved, or onopposite sides where an irregular shape box is in-l volved, and thenumber of tongues and cooperating sockets, while governed to an extentby the cross-sectional size of the box, may be varied within reasonablelimits according to the preference of the manufacturer or particulartrade or individual customer.

In the drawing quadrilateral sockets, recesses or holes 3 andcooperating tongues l have been illustrated, but the shape shown is notessential, any shape suitable to the purpose may be employed.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

l. A receptacle comprising two paper board sections, one of saidsections bepng provided with integral resilient tongues having abruptfree faces, and the other yofsaid sections beingformed With cooperatingsockets having upper and lower edges, and means for holding saidsections spread and resisting their deformation to maintain said tonguesand sockets respectively, in correct, cooperating, interlockingrelation, said tongues, in the assembled relation of the parts,extending at an inclination into the respectivesockets, and each saidtongue engaging with its freeedge face the opposed upper edge of itscooperating socket and engaging with its laterally outer face the loweredge of said socket, at a point intermediate its point of connection toits corresponding section and its free edge face, to limit its latsaidtongues to an inclined angle of engagement with the upper edgesrespectively of said sockets, and to brace each of said tongues at apoint intermediate its point of connection to its corresponding sectionand its free edge face. to prevent strain and buckling v under load.

3. A paper board receptacle comprising a body section, means formaintaining it in spread relation and resisting its deforma- Jcion, anend section having a lip adapted to receive the lower end portion ofsaid body section, and interengaging means for locking said sectionstogether in normal assembled relation, said means comprising a pluralityof resilient tongues integrally formed on one of said sections, each ofsaid tongues having a free edge, means for presenting said tongues at anangle of inclination for engagement with a plurality of sockets ofcorresponding size and shape stamped out of the other of said sections,and means for bracing each of said tongues at said angle of inclination,at a .point intermediate its point of connection to its correspondingsection and its free edge.

In testimony whereof, I have signed my name to this specification atWashington, D. C., this 26th day of July, 1924.
